FAN

Filed June 8, 1954 INVENTOR l A32 2541 (Z6 25 ATTORNEY Patented June 18, 1935r UNITED STATES PATENT omer 5 Claims.

invention relates to improvements in fans, particularly to a ian, the propeller blades of which are operated by hand, and which` can conveniently be carried on the person, either in a pocket or in a handbag, or the like.

It is one of the objects of my invention to provide a fan, the housing of which has preiera'biy 'the shape of an aeroplane, the representation of the wings of which present a secure hold for two of the fingers oi the operators hand, while a third finger is operating the fan.

One ofthe primary objectsof my invention is the provision of a manually operatable fan, the Working parts of Which are extremely simple and noiselessly operating, take up a minimum of space and are compactly arranged Within a housing made in two easily moldable and ready to be united parts presenting a pleasing and elegant exterior shape which may be further enhanced by suitably coloring.

Another object of my invention is the provision of a pocket fan', the spindle of the main operating gear of Which is displacea'biy arranged within the housing in which isA also located a rack in engagement with a pinion formed with said gear, so that upon the operation of the rack by means of the spring mounted operating bar, the gear is brought into engagement with a pinion which carries on its spindle, outside of the housing the fan, to operate the same, and the gear is separated from said pinion so that the fan is receiving a new impetus upon each operation of the operating bar.

Still another object of my invention is the provision of a manually operated fan in which the Working elements, as well as the operating spring mounted bar are located in the central axis of the fan so as to form a smoothly working, readily actuated whole.

A further object of my invention is the provision of a loi-partite housing for the fan, the parte of which are readily united by suitably arranged grooves' and pin connections to form a compact whole the interior of Which has suitable depressions and ridges for the accommodation of the fan operating elements.

A still further object of my invention is the provision of a manually operated pocket fan, the propeller blades of which are arranged and held in a novel manner within a one-piece boss, and are provided with suitable abutments permitting the fan blades to assume a correct operating position While they may conveniently be folded when not in use. It Will be clear that the propeller blades may be removed from the boss Lterial part of this disclosure:

and suitably replaced by other movable bodies or elements such as for instance toys, adapted to be operated by the same means normally operating the fan blades.

These and other objects and advantages of my invention Will become more fully known as the description thereof proceeds and will then be specically defined in the appended claims.

In the accompanying drawing forming a ma- Fig. l is a plan view of 'a pocket ventilator or fan constructed according to my invention.

Fig. 2 is a side elevation thereof.

Fig. 3 is a plan View of the fan after removal of the cover to illustrate the inner construction.

Fig. 4 is a longitudinal section on line il-4 of Figure 3.

Fig. 5 is a cross section on line 5-5 of Figure 3.

Fig. 6 is a detail View illustrating the attachment of the fan bladesv in their holder.

Fig. 7 is a section on line 1 1 of Figure'.

As illustrated, the bi-partite body of my fan constitutes substantially a representation of an aeroplane, and its two parts or halves iii and f Il are readily molded of suitable material and beautifully colored or enameled on the outside.

The parts i0 and H are each formed with laterally extending Wings 2 and iii, providing a convenient hold fortwo of the nngers of the operator, while another ringer is engaging the substantially crescent shaped operating member ifi.

Part i! has on its inner face projectorsv i5, and pins il formed therewith, while part lil has similar projections i6 and pins adapted to engage suitable depressions I8 and holes I9 in part i! to rmly unite both parts.

Both parts have formed in their interior complementary depressions 2li, 2l in which are located the fan operating elements hereinafter' more fully to be described, and the end parts of the fuselage have formed therein elongated axially disposed channels 22 supplementing one another to form an endwise open guide for a sleeve 23 on an operating rod 24 to the outer end of which is secured member I4.

A spring 25 is Wound about the rod 24 and rests with one of its ends against the inner end of sleeve 23 and with its opposite end against the inner end Wall 26 of channel 22.

To the inner end of operating rod 24 is secured one end of a frame composed of two parallel loop members 21, 28. Member 21 is formed as a rack bar the teeth 29 of'which extend inwardly into its loop and mesh with a pinion 30 on a spindle 3|.

Integral With pinion 30 is formed on spindle 3| a comparatively large gear 32, and the ends of spindle 3| are displaceably mounted in slots 33, 34 of the housing parts I0, Il, so that the gear can be brought upon the operation of rod. 24, into and out of engagement with a pinion 35 on a spindle 36, the lower end of which is journaled in a depression of part while its upper Vend extends through an opening in part I6 and carries the boss 31 for the fan blades 38, 39, 4Q. The hub of the gear 32 is equipped with a disc 3| ensuring for the spindle 3| a vertical position during the displacement of the spindle in slots 33, 34.

The boss is made in one piece by bending its material upon itself to form a housing for the ends of the fan blades, and has in its center a socket 4| for the reception of the spindle 3E, the upper end is mounted as at 42 to the upper plate of the boss. The fan blades may be removed from the boss and replaced by suitable elements or other movable bodies as for instance toys or the like to be actuated during the operation of the spindle 36 in the `same manner as the fan blades.

The wings or blades of the propellers or blades 38, 39 and 40 have at their inner ends shoulders or recessed abutments 43 `formed therewith, which during the operation of the fan are engaged by an abutment 44 of the fan boss to operate as afan, while in their inoperative position they can be folded upon one another.

Each fan blade is composed of two portions angularly disposed to one another.

The operation of my fan will be clearly understood from the above description and by simultaneous reference to the drawing, and it will be clear that upon an inward pressure exerted on rod 24 against the tension of spring 25 the rack 2B will operate pinion 30 to rotate gear 32 and at the same time displace the gear spindle 3| in the slots 33, 34 so that gear 32 is brought into engagement with pinion 35 on the fan spindle and the fan will start to revolve, while upon the release of the pressure the spring Will vdisengage gear 32 from pinion 35, so that the fan will receive a new impetus at an inward operation of rod 24.

It will be understood that I have described and shown the preferred form of my invention only as one example of the many possible ways to' practically construct my fan, and that I may make such changes in its general arrangement and in the construction of its minor details as come within the scope of the appended claims without departure from the spirit of my invention and the principles involved.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. A pocket fan comprising a bi-partite slotted casing having substantially the form of an aeroplane, each casing part formed with suitable depressions supplementing one another, a propeller, a spindle carrying a pinion and means in the depressions of said casing parts to operate said propeller said means comprising a spindle displaceably journaled in the slots of said casing, a gear on said spindle, a rack bar in said depressions, a means integral with said gear and in mesh with said rack bar, and means to alternately engage said gear with the pinion on said propeller spindle.
